Loading an MDI form from Sub Main()

I've just started playing with VB.NET and thought I would start with opening an MDI form.
My app starts from a Sub Main() and I used the FormName.Show() call to open the MDI form but the MDI form open and closes itself straight away (unlike VB6).
I even built a VB6 app that just opens an MDI from a Sub Main() and converted it to .NET and it did just the same.
How do I stop the MDI form from closing itself as soon as it's loaded.

Cheers,
Mark.

Hi,

You have to use the instance name of the form as follow:

Dim MainMenu As New Form1()
Application.Run(MainMenu)

Thanks
